I have read somewhere that scientists think that europa may have an underground ocean.
The scientists think that Europa can have the life on it.
Icy Caps
A thick layer of ice
Many scientists believe that Europa may hold water, or at least ice which could mean there is a possibility of life on one of Jupiter's moons.
Europa - a moon of Jupiter.
Scientists believe that there is liquid water, under the crust of Europa.
A saline ocean beneath it's crust.
active volcanoes Ice several miles thick, and oceans of liquid water beneath the ice.
There may be life under Europa's vast oceans. It is cold, but heat from the moon's core and Jupiter's magnetic field may make it habitable for organisms under the ice.
Scientists accept that Europa may have life because it has liquid water on it.
It may have oceans of liquid water under its layers of water ice. Scientists want to know if these oceans (assuming they are there) contain any forms of life.
